During the drying process of lemon slices, the surface is very likely to be crusted, but the inside of the lemon slices is not wet, which is a kind of false drying. The small Tips of the high-quality dry slices made by the lemon slice dryer is to stop the lemon slices when they are dried to a certain degree during the baking process, and then re-bake the second time. Finally, the lemon slices can truly maintain the original color. drying.
The steps of using an air energy dryer to make a lemon slice dryer:
Step 1: Select high-quality lemon fruit, carefully clean the lemon fruit, there are salt water cleaning method, soda water cleaning method or ultrasonic cleaning method and so on. The main purpose is to clean and remove pesticide residues or wax.
Step 2: Use hand or lemon slicer to cut the fruit into slices of about 4mm, pay attention to the thickness to be uniform, the error should not exceed ±1mm! In addition, lemon seeds should be removed to avoid affecting the drying effect and the taste of lemon slices.
Step 3: Place the lemon slices neatly on a ventilated tray, avoid stacking them, first use natural wind and light to remove some of the water from the lemon slices. Transfer the lemon slices that have been air-dried for one day to the air-energy lemon drying room. Set the dryer temperature to a low temperature range of 40-50℃. The water in the lemon slices will slowly evaporate and be discharged during the low-temperature drying process. The drying process is about 12- 13 hours.
Step 4: Put the rack cart containing lemon slices in the drying room, or set up a special regain room, and place the rack cart in the regain room for a period of regain. The surface is now dry. The main reason is that the lemon slices are seriously deformed under hot air drying, and the surface is oxidized to form a dense protective layer, which is not conducive to the continued evaporation and drying of water. After being left for a period of time, the moisture in the lemon slice migrates to the surface of the lemon slice, and the surface will soften. When it is found that the surface is wet by hand pinching, push the rack cart of lemon slices into the drying room again for secondary drying and re-bake.
Why must we use a lemon dryer with heat pump technology
1. The heat pump dryer is used to fully dry the lemons, which has low energy consumption during the drying process and effectively reduces operating costs. 2. The drying process is well ventilated, and the surface of the lemon is heated evenly, without manual entry for turning. The lemon gloss is maintained, and the quality of the finished product can be unified without manual separation. 3. Control the corresponding parameters of lemon drying, intelligently control the problems in the drying process, and intelligently handle abnormal situations. 4. The drying process is safe and reliable, and there is no danger of overheating or burning during the drying process. 5. Automatic temperature and humidity control, high accuracy. Effectively avoid the phenomenon of non-drying or excessive drying caused by manual operation, reduce labor intensity and reduce operating costs. The lemon dryer is not only environmentally friendly, but also energy-saving. The drying process is hygienic and pollution-free, and the color is better than ordinary dry ones.
